LONDON and RALEIGH, N.C., May 09, 2022 (GLOBE NEWSWIRE) -- Verona Pharma plc (Nasdaq: VRNA) (“Verona Pharma”), a clinical-stage biopharmaceutical company focused on respiratory diseases, announces the presentation of an abstract demonstrating ensifentrine met all safety objectives in a through QT (“TQT”) study at the American Thoracic Society International Conference (“ATS”) 2022 taking place on May 13-18. The abstract is published on the ATS website and in the peer reviewed publication, American Journal of Respiratory and Critical Care Medicine.

The study results, first reported in December 2021, demonstrated no clinically relevant effects in measures of cardiac conduction including QTcF, PR and QRS intervals were observed with either 3 mg or 9 mg inhaled ensifentrine dose at any time point over 24 hours.

About Ensifentrine

Ensifentrine (RPL554) is an investigational, first-in-class, inhaled, dual inhibitor of the enzymes phosphodiesterase 3 and 4 (“PDE3” and “PDE4”). This dual inhibition enables it to combine both bronchodilator and anti-inflammatory effects in one compound. Ensifentrine also activates the Cystic Fibrosis Transmembrane Conductance Regulator (“CFTR”), which is beneficial in reducing mucous viscosity and improving mucociliary clearance. Ensifentrine’s mechanism of action has the potential to alleviate respiratory symptoms such as breathlessness and cough and work against inflammation associated with COPD or inflammation triggered by viruses.
